I like a lot of Corey's lyrics in his songs for Slipknot and Stone Sour. Course some are whack, but I find that with every songwriter. Man, all I can tell you is write with feeling, what your feeling, involving your emotions. As long as the lyrics are emotional and have feeling to you than I would be happy with that. A lot of good nu-metal (which is hard to find) can have some really emotional lyrics. I don't really consider them nu-metal, but I would suggest listening to some of Cold's music. All 3 of their cds are very emotional and it is easy to find truth in the lyrics, which is hard to find today.
